Monday night's episode of The Tonight Show featured the popular English Actor Daniel Radcliffe in the guest seat. In addition to the regular interaction, the former Harry Potter star sportingly accepted the host's challenge to rap the famous Blackalicious' "Alphabet Aerobics" song. Being interested in rap music, Daniel was able to complete this rap and also received a thunderous standing ovation from the audience for his performance.  Even the host Jimmy Falon applauded the actor's remarkable rapping abilities. Soon after he finished the rap, the video of Daniel's performance went viral and has already received thousands of clicks from different corners of the world making it one of the most trending viral videos of this week.

During his interview on the Tonight Show, Daniel mentioned that ever since childhood he has harbored a fetish to memorize difficult lyrics and fast songs. As a result, rap songs were always interesting to him. Radcliffe also revealed that he was amongst the first ones in his class to know every word in the lyrics of Real Slim Shady at a very young age. On hearing this, Fallon handed him the mic with a request to perform the Blackalicious' "Alphabet Aerobics" song. 

The song is well known for its tongue twisting lyrics and really fast beats. But, Daniel did not face any of these difficulties and was able to rap his way fabulously delivering a superb performance that too in front of a live audience. The structure of this song is extremely unique and that's what makes it so interesting. Divided into several couplets, this song covers every letter from A to Z. However, every couplet is made of words starting with the same letter. This twist makes this song a cult classic as well as extremely challenging for several other singers. Also, this song was launched in the year 1999 and still remains one of the best known tracks of Blackalicious.
